FLEDnWA'lER REGU LTR SPECIFICATION forming part of Letters Patent No.683,630, dated October 1, 1901.

Application filed October 22,1900. Serial No. 38,860. (Noimoflel.)

10 all whom it nir/ty concern:

Beit known that I, HENRY HERMAN WEST- I NGHoosE,a citizen of the UnitedStates, resid' ing at Edgewood Park, county of Allegheny, 5 Stute ofPennsylvania, have invented or discovered e certain new and usefulImprovement in Feed-WeterReguletors, ofwhich improvement the followingis a. specification.

My invention relates to feed-water regulators for boilers, and has forits object to provide an improved form of regulating-valve which willnot stick to its seat, but one which will always be free to move underthe action of a. ioat or other menusv controlled by the Water-level inthe boiler.

Heretofore reguletingl vnlves have been used which were held againsttheir seats by a. continuous pressure .end it wes found that such valvesvery soon became stuck to their Seats, owing to the friction andaccumulation of sediment, so that the valves would not open and closeproperly under the notion of a. float to regulate the supply of water tothe boiler.

Myinventiou consists in en improved form of reguletingwelve so locatedin n. Writer-pipe connectedto the pump that the suction-stroke of thepump tends to draw the valvefroin its sent nud mee-ns controlled by thewater-level in the boiler for moving said velve on its seet or parallelwith its seat, whereby the valve will be opened or closed according tothe height of the Water in the boiler. By

' this means the valve is loosened from its seat et each stroke of thepump and is thereby balanced, so that there will be no friction orsticking of the velvc; but the saule may be freely operated by the iioutor other means governed by the Water-level in the boiler to open endclose the valve.

I have illustrated my improvement in the accompanying ings, in which-Figure l is n diagram showing the boiler, ieedpurnp, supply-tank, .endthe various pipe :2, e sectional view showing t ol regulating-volvo, andFig. El fcai View showing a. modified construction o1 valve adapted tobe used as s.

suction-volvo of the pump.

As shown in Fig. l, the Seed-pump l is con-A nected to the supplytenk 2by the suctioni pipe 3 and to the boiler l by the delivery-pipe 5, thesepipes being supplied with the usual check-valves. Thepump maybe operatedin any convenient Way, as by a. belt-pulley and crank-shaft, or in casemy device is applied to an automobile the pump may be operated from aWheel or axle of the carriage. Another pipe 9 is connected directly tothe pump and leads to the regulating-valve casing 10, from which theoutlet or return pipe ll leads to the bottom of the supplytank 2. As a.means for controlling the regulating-valve according to the height ofWater inthe boiler I have shown a lient 2l, located in a float-chamber6, which is connected to the boiler by pipes 7 and 8. The iioat isadapted to rock the shaft 22, which extends outside the chamber and isprovided with un arm 23, on one end of which is located thebalance-Weight 24, the other end being connected to the erm of the valveby means oi the rod 25. It is obvious in the boiler may be used foroperating,r the regulating-valve. v

In the vulve-casing l0, es shown iu Figs: 2 nud il, is located thevalve-seat l2, having openings or ports 13 and provided with a.cylindrical extension or bushing which fits within the casing. In thebushing the reguletting-valve Ll is located, which is also provided Withports l5. I have shown the valve lfind valve-seat of conical form, esthis gives n tight joint between the valve and its sent at thedownstroke of the pump; but it is evideut that the valve might be in theform of zt dat disk or some other form adapted to move on its seat orparallel with its sont to open and close theports therein. 'lhe stem 16of the regulating-valve il extends out through thc casing and isprovided :it its outer end with an arm 17, by which the valve may berotated. The valve lei is in direct communication with the pump, so thateach suction-stroke of the pump tends to drew the vulve owzty from itsseat, while et each down wurd stroke the valve is forced against itssont by the water-pres sure.

In Fig. 2 is shown n. light spring 18, which maiy be used to partiallycounteract the effect of the suction` on the valve and prevent the seinefrom moving away from its sont; but

that other ineens controlled by the water-level IOO - even when thespring is usodthe volvo will be loosened from its seat at each stroke ofthe pump, so that it will be balanced es to'pressure and therewill be nofriction between thevalve and its sont vto conse the same to stick orvto prevent its free rotation under the sction o' the float.

In Eig! 3 Vl here illustrnted it slightly-modi- Yfied form in'which u.sliding joint 19 is profree o ouin for the essere of water from D b theteck or pipe ll through the ports of thei' valve to the pipe 9, Whetherthe ports 13 und 15 in the velve und its 'sect happen to be in registeror not, und the water will be drawn into the pump. Then et the downwardstroke of the pump the Water will be forced into the boiler or beck intothe tenir according as the ports in the regulating-waive le are holdclosed or open by means of the floot. "lu this wey the regulating-vulve'xunybense'd as e. sncton-vslveof the pump and thershutfo cock 2O .inthe suction-wipe 3 maybe closed,

or seid suction-pipe may be dispensed With altogether.

The 'operation of my device is :is follows: When the Water becomes lowin the boiler, the iioot rotates the .vulve ll to close the seme, sothat the ports l5 do not register with the ports 13 in the valve-sent.Consequently the pressure et each downward stroke of the' pumpforcesrthe vulve le against its sent and prevents any waiter fromreturning to the tenis' through pipe ll. Then the feed-pump l, which isoperating continuously or when. the carriage is running, lrewswater fromthe Supply either through pipe 3 and its check-valve or through pipo liand the reguloting-vulve and forces it into the boiler through pipe 5.vAs the Water in the boiler rises to a, point nt or above the normalwitterlevel the float rotates the vulve le, so as to open the portsthrough the valve-sect. Then the water from the ypump will be dischargedbeck into the tank through pipe 1l, and no more writer will enter theboiler n util the wetter-level therein lues lowered sufficiently toallow the liest to close the portsI of the reguloting-val ve. The waiterwill then be supplied to the boiler again, as before described.

The Valve. is free to be rotated by the Hout et all times, sinoe'it isloosened from its seat et each suotiowstroke of the pump, und thisloosening of the valve from its sont stench stroke of the pump not onlybalances the valve as to p:essnre,bnt prevents the nocumulation ofsediment or corrosion, which would tend to'ceusee. sticking of thevalve.

Hoving now described my invention, what l cle-iin as new, and desire tosecure by Letters Potent, is-n y l. ln o feed-water regulator forboilers, the combination With :L feed-'pump und a pipe or :tregulating-valve so located in the said pcssngethet the .suction of thepump tends to drew the valve sway from its sent, and means controlledbythe Waiter-level in the boiler for moving seid valve parallel with itssent to open sind close said volvo.
